Matakan kariya da baturi ya ɗauka:
Batirin lithium-ionsel sun cika cajin wutan lantarki sama da 4.2V kuma zasu fara nuna illa. Mafi girman ƙarfin wutar lantarki mai yawa, mafi girman haɗari. Lokacin da ƙarfin lantarki na tantanin lithium ya fi 4.2V, ƙasa da rabin atom ɗin lithium suna kasancewa a cikin ingantaccen kayan lantarki, kuma ɗakin ajiyar yakan rushewa, yana haifar da faɗuwar ƙarfin baturi na dindindin. Idan an ci gaba da caji, yayin da ma'ajiyar ma'aunin wutar lantarki ya riga ya cika da atom ɗin lithium, ƙarfen lithium na gaba zai taru a saman kayan lantarki mara kyau. Waɗannan ƙwayoyin lithium za su yi girma lu'ulu'u na dendritic daga saman anode a cikin jagorancin ions lithium. Waɗannan lu'ulu'u na ƙarfe na lithium za su ratsa ta cikin takarda diaphragm kuma su ɗan ɗanɗana ingantattun na'urorin lantarki masu kyau da mara kyau. Wani lokaci baturin ya fashe kafin gajeren zangon ya faru, wannan yana faruwa ne saboda a cikin cajin da aka yi da yawa, electrolyte da sauran kayan za su fashe su bayyana gas, yana sa harsashin baturi ko bawul ɗin matsin lamba ya kumbura, ta yadda iskar oxygen ta shiga cikin amsa tare da tarawa. na lithium atoms akan saman magudanar lantarki, sannan ya fashe.
Saboda haka, lokacin cajibaturi lithium-ion, dole ne a saita iyakar ƙarfin lantarki na sama don yin la'akari da rayuwa, iya aiki, da amincin baturin a lokaci guda. Madaidaicin iyakar ƙarfin caji shine 4.2 V. Hakanan ya kamata a sami ƙarancin ƙarfin lantarki lokacin fitar da ƙwayoyin lithium. Lokacin da ƙarfin tantanin halitta ya faɗi ƙasa da 2.4V, wasu kayan za su fara lalacewa. Kuma saboda baturin zai fitar da kansa, tsawon lokacin da kuka sanya ƙananan ƙarfin wutar lantarki zai kasance, saboda haka, yana da kyau kada ku sauke zuwa 2.4V kafin tsayawa. Ƙarfin da aka fitar a lokacin daga 3.0V zuwa 2.4V kawai ya kai kusan kashi 3% na ƙarfin baturin lithium-ion. Saboda haka, 3.0V shine manufa yanke-kashe ƙarfin lantarki don fitarwa. Lokacin caji da fitarwa, ban da iyakancewar wutar lantarki, iyakance na yanzu shima ya zama dole. Lokacin da halin yanzu ya yi yawa, ions lithium ba su da lokaci don shiga ɗakin ajiya kuma za su tattara a saman kayan.
Wadannanions lithiumsami electrons da crystallize lithium atoms a saman kayan, wanda yayi daidai da yin caji kuma yana iya zama haɗari. Idan baturin baturi ya fashe, zai fashe. Don haka, ya kamata kariyar batir lithium-ion ya ƙunshi abubuwa aƙalla abubuwa uku: iyakar babba na cajin wutar lantarki, ƙarancin ƙarancin wutar lantarki, da babban iyaka na yanzu. Babban fakitin baturi na lithium-ion, baya ga ƙwayoyin baturi na lithium-ion, za a sami farantin kariya, wannan farantin kariyar yana da mahimmanci don samar da waɗannan kariya guda uku.
